Specification of Letters Patent.

Serial No. 758,173.

In order to arreoniplish the desired result. j

use is made of two separate orystallizers and two separate kettles. the kettles having rertieal niorenient to permit olrunning the resultant liquid in one erystalhzer into a kettle to he t'ransl'errtal to the other er r:-;tallizer.

A pra tieal elnhodinu-nt ot' the invention is represented in the :n-eoinpairviag drawings forming a part ol' this spei-ilieation in whii'h similar ehara 'ters ol' rel'erenee indir-ate eorresqioinling parts in both \iows.

Figure l is an end elevation of the apparatus, ono of the er \'stalli7.ers heing omitted; and Fig. 2 ts a seetional side elevation of the saute. parts heing shown in eleration.

in the (.(JIlSll'tU'lltHl til the apparatus use is lnade'ol' two envst'allizers and .\.spare-'l apart. and of the usual eonstritetion, that is. eat-h er \'stallizer is provided with a res sel l) for the reeeption oi a molten metal, the \tH'il'l lltllltj inelosed in a suitahle shell rpl' lifitlt'tl. at the hottoni with heating nnl) t'or heating the eontents ol the \fes sol li. steam supp'l pipe l) extends .into the vessel it at the lower end thereol' .lo disrharge stealn under a halite plate l.

tho steani stl'YitiQ to eool and agitate the. ads. as i well lcnown in earl-yin;- out the erystalllZution pl-oi-ess. l laeh ot' the '\'es.-:els l is also provided with a valved drain pipe (l for earnviny oil the liquid as hereinalter more. l'ully explainod. intermediate;the r-rystallizers and A aro arranged two transl'errin gkettles it and ll. ol' whieh the kettle ll i provide on opposite sides with valved drain pipes l and l l'or draining the oontonts ol this kettle. into either of the. eiw stallizers l\ or1\, and the kettle ii is likewise. provided with ialved drain pipes I l for draining the eontents of this kettlo into either ol the. euystallizers x\ or A, as hereinaft r inoro l'ully explained. 'lhe ket:

iii. and a. liquid having .277,

tles it and ll are adapted to he raised and lowered into either a drainin; or receiving position. that is. when in lowermost position the kettle is adapted to reeeire the liquid from the. er stallixer or .t on opmiing the t'tiltt'fillotttllllg drain pipe. and when the. kettle is in an uppernnst position its eontents can he drained into the t' illthlltllltllllg ei ystallizer A or on opening the corresponding drain pipe I, I, I or l'. The kettle it and ll are also provided with heating means for keeping their r-ont nts in a molten eondit-ien.

in order to alternately raise and lower the kettles it and II. use is prel'erahly made ol' :1 eahle .l r t 't l't'tl at its ends to the upper ends of the kettles ll and ll. The rahle J passes over p uide pulleys K journaled in a suitahle overhead strueture ll. and the eahle .l winds and unwinds on a drum N journaled on the overhead strueture I1 and harin its shalt 1\' provided with a wheel IV eonneeted with other tllltt'llllltl) or a motor for rotating the. drum X alternatelv in opposite direetions with a View to raiso one litlllt. into draining;position while havering the other kettle into reeeiringz; position.

3y reteren e to the drawings, it will he notieed that. the erystallizers A and A are mounted sullieiently high. so that metal may iit tapped l'roni a enrstallixer into a transl'er hettle.

'lhtoperation is as follows: lresulning that the apparatus is to he used 'l'or retining a metal eontaining' .207; iii. and presuming that the orysta lizer is tilled with a lnetal eonlultlinfi ahont- 20% Hi. and the. ei'y'stah liZol' .t' eontains lne al having ahout .tlHSf/ lii.. the translerrin ij kettle ll is empty. and the transferring kettle ll eontains liquid having! ahout- .1521 lii. ohtained l'ronl the er \'stalli'/.er hy a previous operation. A er \:-;tallixation operation is now earried on in erys allizer A. The result ot' the er lstalli'/'.alion operation in the. erystallizer A is the formation ol' er ystals eontaining .lfi'fl/ lti. 'lhis liquid is run into the transl'errinp; kettle It and is then ltlttUl'til l'roln the latter l'or l'urthel' working. and the eonteuts ol the lteltlu ii are. now translerred into the crystallizer A, so that. the latter now contains crystals and a liquid having eaeh the same pereentago ol' hisnulth, that is .l5'/-.

'lhe erystallization opeialion in the. eryscarried on in the crystallizer A to produce a liquid having 20% Bi. and crystals contaming about .11% Bi. .'The liquid is tapped into t e transferring kettle H. The liquid 'inkettle H is next transferred into the crystallize'r A which contains crystals of the same grade 11% Bi. The remaining con- "tents-of thecrystal'lizer A containing about 063% Bi. are now tapped into the transferring kettle H and part of this metal is 15 delivered outside as purified lead, but a portion equal to the re ular liquid portion is retained in the trans erring kettle H. The

liquid containin about Bi. in the transferrin kette H is now tapped into 20 the. crystallizer A and a new charge of .metal also containing 20% Bi. is added to fill-the crystallizer A. j

The next crystallization operation carried on in the 'crystallizer A produces a liquid containing about-.15% Bi. andcr stals containing about 085% Bi. Theliqui istransferred to the transferring kettle H and the contents of the transferring kettle H containing about 063% Bi. is tapped into the crystallizer A. A crystallizatlon operation is now carried on in the crystallizer A containin a liquid of about 20% Bi., so that a liqui is produced of about .27 Bi. and crystals containing .about .15% Bi. The liquid of about.27% Bi. is tappedinto the transferring kettle H and is removed for furthertreatment outside of the apparatus. The liquid in'the transferring kettle H containing about 15% Bi. is now tapped into the 40 crystallizer A.

The crystallization operation is now carried on in the crystallizer A to produce a li uid containin about 11% Bi. and crysta s containing a out 063% Bi. The l uid is run into the transferring kettle H w ile the crystals remain in the crystallizer A. The c stallization operation is now carried on in t e crystallizer A to producea liquid containing about 20% Bi. and crystals containing about .11% Bi. The liquid is transferred to the transferring kettle H and the liquid from the transferring kettle H containing about .1l% Bi. is tapped into the crystallizer A. The liquid of the crystallizer A containing 068% Bi. is now tapped into the kettle Hand the liquid contained in kettle H, and a new charge of metal containing 20% Bi., and in quantity sufiicient to fill the crystallizer A is now passed into the latter. A crystallization operation is now carried on in the crystallizer A to roduoe liquid c ntaining about 15% Bi. his liquid goes to kettle H. Crystallizer A now contains crystals with -.085% Bi. Part of the liquid in kettle'll is put into crystallizer A and part delivered as a uri fied lead. The result is now a. con ltion practically the same as at the beginning and the above-described operation is repeated. a

From the foregoing it will be seen that b the operation described, the metal is gra ually refined and run off as purified lead and an enriched lead'periodically discharged for further treatment, the whole operation being .carried on by the use of two crystallizers and two transferring kettles as de:

scribed.

Having thus described my invention, I claim as new and desire to secure by Letters Patent: J

1. An apparatus formfining lead, comprising two stationary crystallizers, two

movable kettles, and means for moving the kettles alternately into receiving position relative to one or stallizer and into transferring position re ative to the other crystallizer.

2. An apparatus prising two spaced and fixed crystalhzers, a pair of transferring kettles arranged between the said crystallizers, and means to alternately raise and lower the said kettles, one into receivin position relative to one cry'stallizer-and t e other into transferring position relative to the other crystallizer.

3. An apparatus for refining lead, comprising two spaced and fixed crystallizers, a pair of transferring kettles arranged between the said crystallizers, an overhead frame to su port a drum, a cable on the said drum and having the ends connected with the said kettles to raise one while lowering the other, and driving means for rotating the drum alternately in o pcsite directions.

In testimony whereof name to this specification in the presence of two subscribing witnesses.
